Why are chocks used when parking a trailer without spring brakes?

• A. To prevent the trailer from rolling due to air leakage
• B. To secure the cargo inside the trailer
• C. To assist in the coupling process
• D. To stabilize the trailer in high winds

Answer: (A)

Chocks are crucial for preventing a trailer from rolling when it is parked without spring brakes. When air brakes are not in use, trailers can be at risk of movement due to gravity or external forces. Chocks create a physical barrier that prevents the trailer wheels from rolling, ensuring safety by securing the trailer in place. This prevents any potential accidents that could occur if the trailer were to roll away, especially on inclines or uneven surfaces. The use of chocks addresses concerns about air leakage impacting braking systems, which is particularly relevant when spring brakes are not engaged.
